proposal: Pipeline Operator for Go

[KINGMJ]

Proposal Details

Motivation

The pipeline operator (|>) is a feature seen in languages like Elixir, which allows for more readable and maintainable code by chaining function calls. Introducing a similar operator in Go can simplify complex function chains and improve code readability.

Proposal

Introduce a pipeline operator (|>) in Go that allows chaining function calls. The operator will pass the result of the expression on its left as the first argument to the function on its right.

Example

// Current Go code
result := multiplyByTwo(subtractThree(addOne(5)))

// Proposed syntax with pipeline operator
result := 5 |> addOne |> subtractThree |> multiplyByTwo

If there is no error handling improvement, the scope of application is very limited.
I still hope that official can introduce some error handling improvement. The most likely scenario is an error handle macro.
